Hello,
I'm facing a bug with winbind. If I request groups for particular domain user,
winbind cache gets corrupted. My winbind version is 4.1.12-23.el7_1 (Centos
7.1, x86_64).
1) this is correct UID to SID mapping:
wbinfo -U 100152
S-1-5-21-3451901064-902568176-4053310204-180212
2) I request groups info for a user:
id -G -n 209459
[reply with 33 groups]
3) I request UID to SID mapping again:
wbinfo -U 100152
S-1-5-21-3135676852-3361659551-265282358-180212
and it is different. So it looks like corruption somewhere. Before I start to
debug, is this a known problem possibly fixed in winbind 4.2.x version?
